DeprecationWarning with iPython during executing certain commands in the console.

PS0: Downgrading ipython to 6.5.0 solves this.

Problem Description

A “DeprecationWarning” is triggered when executing certain commands in the console,like “import a as b”,but not occurs everytime as described in the senario below.

Python 3.6.6 |Anaconda, Inc.| (default, Jun 28 2018, 11:27:44) [MSC v.1900 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.

IPython 7.0.1 -- An enhanced Interactive Python.

import nilmtk

import nilmtk as nt
d:\anaconda3\lib\site-packages\ipykernel\ipkernel.py:444: DeprecationWarning: `input_splitter` is deprecated since IPython 7.0, prefer `input_transformer_manager`.
  status, indent_spaces = self.shell.input_splitter.check_complete(code)

import keras as k
d:\anaconda3\lib\site-packages\ipykernel\ipkernel.py:444: DeprecationWarning: `input_splitter` is deprecated since IPython 7.0, prefer `input_transformer_manager`.
  status, indent_spaces = self.shell.input_splitter.check_complete(code)
Using TensorFlow backend.

Moreover, sometimes I need to hit the Enter key twice more to execute a certain command even that command is intact, with which the DeprecationWarning appears possibly.

d:\anaconda3\lib\site-packages\ipykernel\ipkernel.py:448: DeprecationWarning: `input_splitter` is deprecated since IPython 7.0, prefer `input_transformer_manager`.
  status, indent_spaces = self.shell.input_splitter.check_complete(code)

import numpy

d:\anaconda3\lib\site-packages\ipykernel\ipkernel.py:448: DeprecationWarning: `input_splitter` is deprecated since IPython 7.0, prefer `input_transformer_manager`.
  status, indent_spaces = self.shell.input_splitter.check_complete(code)

PS: The first deprecation warning above “import numpy” appears when the command is executed but appears ahead of the command line.

PS1: Have tried in QtConsole just now, it happens too sometimes.

Same problem here on a Macbook with Spyder4 and IPython 7.5.0. Perhaps the issue should be reopend?

In the meantime you can downgrade to IPython 6 to avoid this.
